Iwata are good, but they are overpriced for what they are.
I've gone through a few airbrushes over the years, started with a Paasche suction feed, but ddidnt like it.
Switched to a Tamiya HG superfine which was great. Fine tipped, screw adjustment for the trigger. But, couldnt change the tips of cup at all.
I looked at getting an Iwata, but they are over priced.
I ended up getting an Infinity by Harder and Steenbeck.
Infinity here
Has trigger tension adjustment, click to set trigger position, replaceable cups, can swap the needles/tips etc, and i love it. got it from
here.
I cant recommend it enough.
